AfterFull Roof Replacement in San Francisco, CA
A full roof replacement in San Francisco typically costs between $18,000 and $45,000 depending on roof size, material choice, and slope, and most projects take 3 to 7 working days once permits clear. Birchbark Roofing San Francisco gives you a written price in dollars before any work starts, so you know your exact number before a single shingle gets torn off. If you’re weighing repair against replacement, call us at (831) 228-3330 and we’ll walk you through what your roof actually needs, not what’s fastest for us to sell.
This page covers what full roof replacement involves, what it costs here in San Francisco, and how we keep the disruption to your home and family to an absolute minimum. If you want the broader picture on materials, timing, and the full scope of roofing work we handle, see our Roof Replacement & Installation page.
When You Need Full Roof Replacement
Not every aging roof needs to be torn off. But in San Francisco’s fog-heavy neighborhoods, certain conditions make full replacement the smarter financial call. Here’s what pushes a roof past patching and into replacement territory:
- Widespread granule loss. If you’re finding asphalt granules in your gutters every time it rains, the shingles are shedding their protective layer. In the Sunset and Richmond districts, persistent fog accelerates this breakdown faster than homeowners expect.
- Curling or buckling shingles across multiple roof planes. One or two bad shingles is a repair. Shingles lifting in sheets, especially on the windward side of homes near Twin Peaks or Diamond Heights, signals the roof has hit the end of its service life.
- Chronic leaks that keep coming back. When water keeps finding new paths through an old roof, chasing leaks one patch at a time starts costing more than replacing the whole assembly at once.
- Visible daylight through the attic boards. If you can see light coming through the roof deck from inside your attic, the decking or underlayment has failed. That’s structural, not cosmetic.
- Roof age beyond 20 – 25 years. Most asphalt shingle roofs in San Francisco last 20 to 25 years. If your roof is near that mark and the inspection shows worn flashing, brittle shingles, and failing underlayment, replacement is usually cheaper than continuing to repair.
- Storm damage across a large area. After a heavy winter storm rolls through from the Pacific, scattered missing shingles across multiple slopes often cost more to patch properly than to replace in one clean job.
Our Full Roof Replacement Process
Here’s exactly what happens when Birchbark Roofing San Francisco replaces your roof, step by step, so you know what to expect before we show up:
- On-site inspection and honest assessment. We walk the roof, check the attic, and tell you straight whether you need a full replacement or a targeted repair. If repair makes sense, we’ll say so. If replacement is the right call, we’ll show you why with photos and measurements.
- Written price before any work starts. You get a line-item price in dollars covering materials, labor, permit fees, and disposal. No allowances, no “we’ll see how it goes.” The number you see is the number you approve.
- Material selection with real guidance. We walk you through options from GAF, CertainTeed, and Tamko so you can choose based on your budget, your home’s architectural style, and how long you plan to stay in the house. We’ll tell you which materials hold up best in San Francisco’s salt air and fog.
- Tear-off and deck inspection. The old roof comes off down to the decking. We inspect the wood and replace any rotted or compromised sheets before underlayment goes down. This is where we catch problems that would otherwise hide for another decade.
- Installation with home protection in place. Our crew uses shoe covers at the door, drop cloths through the hallway, and careful scheduling around your family’s routines. If the dog needs to stay inside, we coordinate door access with you. We choose pet-safe products where there’s a choice.
- Clean-up, walk-through, and photo proof. We clear all debris, run a magnet sweep for stray nails, and take a photo of the completed clean-up before the crew leaves. You see the finished roof and the finished clean-up. Then you get your 365-Day Done Right Promise in writing.
Full Roof Replacement Pricing in San Francisco
What does a full roof replacement actually cost in San Francisco? Here are honest ranges based on the projects we’ve done across the city, from the Marina to Noe Valley to the Outer Sunset:
| Roof Type & Scope | Typical Range |
|---|---|
| Small single-story home, asphalt shingle, simple roof (1,000 – 1,200 sq ft roof area) | $18,000 – $24,000 |
| Average San Francisco home, asphalt shingle, moderate complexity (1,500 – 1,800 sq ft roof area) | $24,000 – $34,000 |
| Larger home or complex roofline, architectural shingle, multiple valleys/dormers | $34,000 – $45,000 |
| Premium material upgrades (CertainTeed triple-tab to designer shingles, or Boral concrete tile) | Add $8,000 – $20,000 depending on material |
| Decking replacement (per sheet of plywood, if rot is found after tear-off) | $90 – $140 per sheet |
| Permit fees (San Francisco DBI) | $800 – $2,500 depending on scope |
Several factors move your number within these ranges. Roof slope matters a lot: steep roofs on homes in Noe Valley or Diamond Heights take more hours of labor and more safety equipment than low-slope roofs in the Richmond. Access is another factor – if our crew can’t get a truck close to the house, or if the roof is three stories up on a narrow Noe Street lot, we’re hauling materials farther, and that labor shows up in the price. And of course, material choice shifts the budget significantly: a Boral concrete tile roof costs more up front than an asphalt shingle roof but can last two to three times as long.
The honest way to know your number is to have us look at your roof. Estimates are free. You’ll get a written price in dollars before any work starts, and that’s the number you’ll pay, not a starting point. Call (831) 228-3330 to schedule an inspection.
FAQs – Full Roof Replacement
How long does a full roof replacement take in San Francisco?
Most residential full roof replacements in San Francisco take 3 to 7 working days from tear-off to final clean-up, depending on roof size, complexity, and weather. San Francisco’s fog can slow some adhesive materials, so we build realistic weather buffer into our schedule from day one. Call (831) 228-3330 with your roof’s details and we’ll give you a project-specific timeline.
Is it cheaper to repair or replace my roof?
If your roof has widespread damage, multiple recurring leaks, or is past 20 years old, replacement usually costs less over a 10-year window than continuing to patch. Repair makes sense when damage is localized to one area, like a single valley or a few missing shingles. But if you’re spending $2,000 to $4,000 a year on repairs and the roof is aging, that money compounds fast. Call us at (831) 228-3330 for an honest assessment – if repair is the better call, we’ll tell you.
Can you replace my roof if my kids and pets are home during the job?
Yes, and we plan around it. We schedule door access with you so the dog doesn’t bolt when the crew comes through, we use shoe covers and drop cloths on every interior path, and we choose pet-safe products where there’s a choice. We’ll also coordinate loud work – like tear-off and nailing – around nap times if you tell us what your family’s day looks like. If you need to be out of the house for the noisiest phases, we’ll tell you which days those are so you can plan accordingly.
Do I need a permit for a full roof replacement in San Francisco?
Yes, San Francisco requires a building permit for full roof replacement through the Department of Building Inspection. Our pricing includes permit fees and coordination, so you never have to queue at DBI. We handle the paperwork as part of the written price.
What happens if something goes wrong after the job is done?
The 365-Day Done Right Promise covers every full roof replacement we perform. If the work isn’t right – a leak develops, flashing fails, a material issue appears – we make it right, for a full year after we finish. You’ll have this guarantee in writing, stamped on your job documents, before we start the work.
What Sets Birchbark Roofing San Francisco Apart
Birch bark was one of the first roofing materials: light, tough, and made to shed water. That’s where we get our name, and it’s the standard we hold every roof to. As part of the Cedarwell family of independent local roofing businesses, Birchbark Roofing San Francisco holds every job to the Cedarwell Care Promise. That means four things, every time, no exceptions:
- Clean up like it’s our own home. Shoe covers at the door, drop cloths through the hallway, all debris cleared and photographed before we leave.
- Ask before we move or touch anything. Your patio furniture, your potted plants, your kid’s basketball hoop – they stay where you put them unless you tell us otherwise.
- Respect the family’s time and quiet hours. We show up when we say we’ll show up, and we don’t run nail guns at 7 a.m. on a Saturday unless you’ve asked for that start time.
- Explain the price before the work. You approve a written dollar amount before a single shingle comes off. No surprises, no handshake deals.
Every Birchbark job includes a live person answering your call 24/7 – nights, weekends, and holidays included. Our technicians are background-checked and uniformed, so your family knows exactly who is at the door and on the roof. And we work with materials from GAF, CertainTeed, Tamko, and Boral to give you real options at different price points, not whatever’s left in the warehouse.
